About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20SB
The AirTAC B01-SDA20X20SB is a double-acting, single-rod compact cylinder engineered for tight axial spaces. The B01- prefix denotes AirTAC's application-dedicated (customer-specified) line, meaning this unit is mechanically identical to the standard SDA20X20SB. It delivers 157.1 N of push force and 131.9 N of pull force at 0.5 MPa, utilizing a hard-anodized 20 mm bore and a two-way piston seal for reliable pneumatic actuation.
Because the barrel, rear cover, piston, and 8 mm rod are joined into a short riveted body, it drastically reduces machine footprint compared to round-body alternatives. This specific SKU includes the -S magnet for direct mounting of AirTAC reed or electronic switches along the body grooves, and the -B option, providing a male M6x1.0 threaded rod end for secure load coupling. End-stopping relies on a fixed NBR bumper, which decelerates the piston near stroke end but is not an adjustable air cushion.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20SB Is Used
PCB Depaneling Router
Provides the 157.1 N push at 0.5 MPa required to clamp circuit boards during automated routing, utilizing the short 20 mm stroke and male M6 rod for precise tool mounting.
Blister Pack Sealing
Handles the rapid 20 mm extension to close sealing jigs on thermoforming lines, where the fixed NBR bumper absorbs the end stop within the 30-500 mm/s speed range.
Light-Duty Ejector Pins
Ejects small molded silicone parts from fixtures, taking advantage of the built-in magnet and electronic switch feedback to confirm retraction before the mold closes.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20SB the Right Cylinder?
When sizing this actuator, evaluate your force margins both ways: stepping down to the SDA16 yields 100.5 N of push at 0.5 MPa, while stepping up to the SDA25 provides 245.4 N. The 20 mm bore here offers a safe working load of roughly 94 N (about 60% of its 157.1 N capacity) and can vertically lift approximately 8 kg with a 2:1 safety factor. To order, confirm the 20 mm bore, 20 mm stroke, M5x0.8 port, built-in magnet (S), and male M6x1.0 rod thread (B). Remember that a plain compact cylinder drifts if air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a lock. For position holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-SDA Dedicated Cylinder B01-SDA20X20SB FAQ
This double-acting cylinder generates 157.1 N push and 131.9 N pull at 0.5 MPa, and 219.9 N push at 0.7 MPa. Its theoretical maximum push is 32 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
The B01- prefix simply marks this as an AirTAC application-dedicated (customer-specified) variant of the SDA20X20SB, with no mechanical changes to the bore, seals, or force. It uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. For high-energy cycles, add an external shock absorber.
